SPOTLIGHT AND OPERATING- IWEGHANISHL Application filed Octohor l, 1921. Serial No. 50%,813.

To alZ whom it may concern A Be it known that I. NICOLA firnmmcnns, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and. useful Improvements in Spotlights and Operating Mechanism, of which the following is a specification. 7

This invention relates to an improved spot light and operating mechanism tl'ierefor, and has for its primary object the construction and association of parts whereby the spot light may be used to greater advantage.

An object of the invention is the novel nntnncr of constructing the mecl'ionism so that the light may be given horizontal and vertical movement for properly directing the rays of light.

Another object of the invention is to give the various movements to a spot light-and lock the some iii-any position.

Besides the above my invention. is distinguished, in the improved form of spot light so that the illuminating means thereof. may

be readily removed for positioning-upon vs.-

rious metallic structures.

Witl'i these and other objects in view the invention will be better understood from the following detailed description and the ac eonipenying drawings wherein:

Fig. l. is a. side elevation of my invention.

Fig. is a detail view of :1. port of the spot lightren'ioved and utilized for another purpose.

215 Fig. 3 is o longitudinal sectional view.

Fig. is a. sectional view on "he line d d cl 3.

Fig. 5 is a sectional view on the line 5-;5

Fig. 6 i a sectional view on the line t-6 s diagrammatic view of the Wirrenn n to the drawing: illustrnt one oi the innn constrimtions of my in veiition the numeral 1 designates my liil jgiroved spot light consisting o; a casing" of required shape and having liingrei'l to its front edge the clamping; ring This W clsinping ring is constructed to clamp n ce the flange 4 on the. reflector 5 the .nineting means. This reflector includes .1. socket 6 for supporting the bulb "l' and Jenn ed to and forming the bsseifor the .or is on electric me not 8. Secured he surface the refic tor ere hi2 posts 9 for making the proper connection while at all times allowing for disconnection of the reflector from the casing. By referring to Fig. 52 of the drawings it Will be seen that the light may be readily removed and supported upon any metallic structure such as the frame of an automobile the magnetism of the magnet will properly act to support the reflector. Referring to the diagrammatic view illustrated in Fig. if of the drawings it will be seen that the bulb 7 15 arranged in o. circuit 10 which includes a battery 11 .and a switch 12. T he magnet 8 is arranged in partial circuit 13 braced across the bottery and including a switch 14. Thus it will be seen that the bulb may be illuminated without energizing the magneto or the magnet 8 Insy he energized without illuminating the bulb *5 by closing both the switches 12 and 1 -1 both the bulb and mag not can be rendered active.

The...o;; orating mechanism for my improved light consists of a post 15 which rotatably supports the auxiliary hollow shaft 16, one, end of this shaft is provided with ratchet teeth 1'? while the other end is'i'igidly connected to on arm 18 and a bracket 19. The arm 18 has connection with the cas- .ing 2 as indicated at 20 while the bracket 19 rotntuhly supports the stub shaft 21 that in turn is rigidly connel'fted, to casing .llotatobly supported within the auxiliary hollow shaft it; is a. main hollow shaft 22 which has secured to one end the bevel 23 meshing with the tond bevel 24 that connected to the shaft 21.. The remaining end of the shaft 22 has connected thereto collar 25 rotstahly :ssociated with. any suitable frame. or stationeryswitch 26 that will be connected to the main current coi'nluctingr wires. in this particular instance I eve switch 2%; closed by inserting the plug 27.

As for as l have proceeded it will be seen that by turning one of t. shafts the lamp will he given horizontal movement and by operating theother shaft the lamp will be given vertical movement, thereby enabling the opestor to iiiroperiy direct the rays of light. A main hand Wheel is keyed to the main shaft for sliding movement and s provided with teeth. 1'29 normally forced into engagement with the teeth 17 by the spring 30. A. auxiliary hand Wheel 31 provided h normally forced i o engage n th': t eth on. the l; by

spring 31-. This hand wheel 31 is keyed to the shaft 16 for sliding movement.

From the foregoing description taken in connection with the accompanying draininggs it will be apparent that hy sliding the hano Wheel 28 the some will he tisengzug ed from the teeth 1? so that by turning the hand Wheel the shaft 232 will be operated torgivin horizontal movement to the light; as soon as pressure relieved from the hand Wheel 28 the spring 30 will force the teeth into locking engagement for holding the light in adjusted position. By giving the same action to-the hand Wheel 31 the shaft 16 can be operated. for giving vertical movementto the light.

It is, of course, to he understood that the invention may be constructed in various other manners and the parts ssoeioted. in difl'erent relations and, therefore, I do not desire to be limited in any manner except as set forth. in the claims hereunto appended.

Having thus described my invention what ll claim is 1. in eomhin'ation, a light, it hraeket- Supporting the light for horizontal and vertimil movement, a main shaft having a connection with the light to move it horizontally, a. hollow auxiliary shaft encircling said main shaft and connected to the bracket for swinging the light vertically, a hand Wheel on said auxiliary shaft, 2t second hand wheel slidahly supported upon and adapted to turn said Inzun shaft, said second hand Wheel having locking engagement with. said nun iliary shutttvhen in normal position.
